    My five-person consulting firm needs a dependable partner who can handle our day-to-day IT environment entirely off-site.

Here is what the engagement looks like from my side: • On an average month you will perform regular system maintenance, jump in quickly to troubleshoot anything that crops up, tune performance so laptops stay snappy, and spin up new machines or cloud user profiles whenever we add a team member. • Remote desktop tools, monitoring and management software, and solid security software should already be in your toolkit so you can diagnose issues, patch syst...

    My application handles sensitive user data, so every layer—from the UI down to the database—must be watched continuously for signs of malware and other threats. I want a full-stack developer who can weave solid data-protection practices into the codebase while building out a real-time monitoring solution that flags malicious activity before it escalates. Here’s what success looks like for me: • End-to-end vulnerability monitoring—frontend, backend, and storage—using industry-standard tools or your own lightweight scripts. • Automated detection tuned specifically to malware and virus signatures, with clear alerting to Slack/email or another channel we agree on. • Clean, well-commented code and deployment notes so I can maintain or extend the...

    I’m planning a full-scale systems integration that will let our HubSpot CRM talk seamlessly with our enterprise-grade ERP. The goal is to create a real-time, bidirectional flow of customer, order and inventory data without disrupting either platform’s native workflows.

That means defining the overall integration architecture, documenting data models, selecting the optimal middleware or iPaaS layer, and outlining security, error-handling and scalability considerations. REST and webhook experience with HubSpot is essential, but I’m open to your recommendations on the ERP side—wheth...

    I’m running a self-hosted Odoo v17 instance and I want it to speak with Claude in a strictly controlled, read-only fashion. The goal is for Claude to pull customer-relationship data, inventory figures and any other information needed to generate automated reports—nothing more, no write or admin rights at all. Security is paramount, so I’m open to whichever connection method (API, webhooks, or another highly secure approach you can justify) best keeps the data safe while remaining maintainable with future Odoo and Claude updates. You’ll need to map the relevant Odoo models, handle authentication, and make sure permission scopes remain locked to read-only. Deliverables should include: • A working integration module or middleware script fully installed on my s...

    My personal Facebook profile is locked after I lost the phone that held my two-factor-authentication app. I already went through Facebook’s normal “Forgot password” flow, but because I no longer receive the 2FA code the process stalls and the account remains inaccessible.

Recovering the account must keep all existing data, pages, and business integrations intact. Acceptance will be: • Successful login from my side on a new trusted device • 2FA either restored with a new authenticator or fully disabled by agreement • A short note outlining the exact steps taken so I can repeat them if eve...
